...contribution to a pollution-freeenvironment
Introduction:
We do dream of being a developed country by 2020, but at least to that date, but pollution is a great threat. Earth is beautiful heaven with different people who have a golden heart. But the heaven is converting into hell now a days. It doesn’t matter if the pollution we made, causes danger to us alone, but it causes danger to all the living organism.
What is Pollution?
Pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollution is of many types. The major four were Air, Land, Water and Noise.
Effects of pollution:
Human Health
Environment
Human Health:-
Adverse air quality can cause many diseases and harms to many organisms including humans.
For Example,
HUMAN BEINGS:-
Air pollution can causes respiratory disease, cardiovascular disease, throat inflammation and chest pain
Water pollution causes approximately 14,000 deaths per day.
It is observed that pollution is greater in developed countries than developing countries.
Oil spills can cause skin irritations and rashes. Noise pollution induces hearing loss, high blood pressure, stress, and sleep disturbance.
Lead and other heavy metals have been shown to cause neurological problems....

...our environment is saving wild life creatures. Cutting down trees is killing their habitat and ways of living. How would you like it if someone came into your neighbourhood and started bulldozing the houses down? Many living species have died because of the habitat changes they have to go through. Many oceans and other water bound areas in the world are being polluted by human waste. It’s killing all water creatures and making water unsanitary. If you really think about it, we, as a community, are murderers for polluting animals’ homes and ways of life. We are killing so many creatures each day because of all the waste we don’t care about and dump into oceans. It really is a horrible thing to think about. The first attempt for wildlife conservation was taken during the 19th century according to the North American wildlife conservation model and it was successful also after that so many initiative were attempted like world conservation agency developed by IUCN in 1980 with the assistance of UNEP and WWF, similarly in 1972 wild life conservation act was also enacted in India. These all have the motto to conserve the wildlife. Than for saving the environment steps were also taken after holding the different conferences like Rio conference in Brazil, CANCUN in Mexico, EUEC [energy utility environment conference] in USA etc. But now the situation says that these were not at all successful in their motto because the rate of extinction of...

...﻿The Varying Effects of Pollution on the Environment
James Fields
Indiana University Southeast
Abstract
This paper explores the varying effects of pollution on the environment and human interaction by explaining the history of human’s tendency to pollute and giving several examples that created many regulations that help in decreasing pollution. Many studies in this paper help to explain how pollution is directly related to human interaction such as the study by Keith Gaby that show a correlation between lead pollution and crime rates. Another study by Matthew Ranson uses historical records of crime rates and temperatures to conclude that high rates of violent crimes is directly related to global warming.
The Varying Effects of Pollution on the Environment
“Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it's the only thing that ever has.”Once stated Margaret Mead. In the 50 years since Rachel Carson published the Silent Spring the modern environmental movement began, the world is more polluted and less healthful because our civilization is based on consumerism and greed. Consumerism is the belief that it is good for people spend a lot of money on goods and services. Consumerism can be a good thing creating mass markets, industrialization, and cultural attitudes that ensure that rising incomes...

...Introduction:
Environmentpollution is a much-talked topic of the present time. Our life is so deeply and invariably related to environment that any pollution of it causes dangers and brings about different disasters. In fact, a sound environment is the precondition of a sound living. However, our environment is being polluted in a number of ways. In Bangladesh, the level of environmental pollution has reached high and it is high time we checked environment from being spoilt.
Environmentpollution by business:
Pollution is common phenomenon in Bangladesh. Water, Environment, Air are polluted continuously. Environmentpollution is most common in our country. A report of Paribas Odhidoptor shows that “our environment is polluted double in every year”.
All we see around us are the element of environment Air, Water and oil are some of the main element. But they often pose to be a thread to our life, particularly when they get polluted.
Types of pollution:
1. Air pollution by smoke:
Air is being polluted by the smoke and different gases emitted from various sources. Mills, factories, powerhouse, automobiles produce a lot of smoke which contain carbon-di-oxide, carbon-mono-oxide, sulphur oxide, nitrous oxide and...

...Human Impact on the Environment
Every living thing has an impact on its environment. Therefore a human impact on the environment is inevitable. By simply existing, all species - including ourselves - will imprint their mark on the world around them.
What differentiates us from other species is our ability to greatly overburden our environment with very few limits.
The information regarding our human impact is vast and impossible to cover in one article but I will attempt to cover a basic overview.
For 200 years we've been conquering Nature.
Now we're beating it to death.
~ Tom McMillan
Water Pollution
Perhaps the most obvious examples of a negative human impact on the environment is water pollution. It's obvious we need water to survive but few people realize how much we need and just how much is available. Consider these facts from the United Nations Environment Programme:
* Of all the water on Earth, only 2.5% of it is freshwater.
* Of that 2.5%, less than 1% is available to us.
* Humans each require up to 13 gallons (50 litres) a day of fresh water for drinking, cooking and cleaning. This does NOT take into account the countless gallons of water needed to grow food or care for animals.
* 70% of all freshwater usage goes to irrigation.
According to Organic Farming Research Foundation, only 2% of farms are organic. This means almost...

Topic: Some people believe that the Earth is being harmed (damaged) by human activity others feel that human activity makes the Earth a better place to live. What is your opinion?
Nowadays the Earth faces a number of serious problems, such as the environmentpollution, the increasing population, the fatal effects of nuclear weapons, etc. The problems arising from not just development in terms of science and technology but also the increase in human demands based on population and economy. According to Professor David Karoly from the Department of Earth Sciences at the University of Melbourne, it is time to take urgent action to slow global warming by human activities, because the impacts of human-caused climate change in many natural systems much earlier than previous studies had projected which are being seen (Proof: humans have damaged earth, 2008). There is inconvertible fact that in history of humanity, human causes detrimental effects on earth. Indeed, human activity affects nature and human environment.
For centuries, many activities of human have destroyed ecosystem of the Earth. Deforestation and over-hunting is one of the main causes of this serious situation. The world is very big, but natural resources are not endless. In fact, Dave Gilbert (2012) announced that nearly a fifth of the Brazilian forest has been lost since 1970. That means all of the trees, plants, insects, animals and people who live there...

...OF ENVIRONMENTAL POLLUTIONS
When there are some physical, chemical or biological changes occur in our physical environment it is known as pollution and the substances which brings these changes are known as pollutants. The sources for the pollution can be natural or manmade.
Following are the types of Environmental pollution.
1. Air pollution
2. Water pollution
3. Soil pollution
4. Noise pollution
5. Marine pollution
6. Thermal pollution
7. Nuclear pollution
1. Air pollution: When some foreign particles enters the air and deteriorate its quality is known as air pollution. These particles can be produced naturally or manmade. Dust storms, Bacteria and gases of volcanic eruptions are examples of natural’s sources of pollutants. Gases released from the automobile and the chimneys are the example of manmade pollutants.Major Air pollutants: Carbon monoxide (CO), Ozone (O3), Nitrogen dioxide (NO2), Sulphur dioxide (SO2) and lead.
How to control air pollution?
• Maintaining a healthy distance between the industrial and residential areas
• The chimneys should be constructed tall in size so that the emissions must be released higher up in the environment
• The sulphur must be removed after burning
•...
